Abstract

The behavior of a cylindrical body with a nonaxisymmetric cross section in a horizontally positioned cylindrical cuvette filled with viscous incompressible fluid and performing rotational oscillations is experimentally studied. The effect of vibrational suspension of a heavy nonaxisymmetric cylinder near the bottom of a vibrating cavity at a distance comparable with the thickness of the Stokes viscous layer is revealed and studied. The character of the oscillatory dynamics of the body and its interaction with the cavity boundary are investigated using the high-speed video registration of the process.

充满液体并执行旋转振荡的腔体内非轴对称圆柱体的振动

摘要

实验研究了具有非轴对称横截面的圆柱体在水平放置的圆柱形比色皿中的行为,该比色皿充满了粘性不可压缩流体并进行了旋转振荡。揭示并研究了重型非轴对称圆柱体在振动腔底部附近的振动悬挂效果,该距离与斯托克斯粘性层的厚度相当。使用该过程的高速视频配准,研究了人体的振动动力学特性及其与空腔边界的相互作用。
